Witness: Key Insights into Their Role and Legal Significance

Definition & Meaning

A witness is a person who provides testimony in legal settings, such as trials or depositions. This individual has direct knowledge of facts related to a case and is sworn to tell the truth. Witnesses can be either parties involved in the case, like the plaintiff or defendant, or neutral individuals who have relevant information. Their testimony must adhere to established rules of evidence.

There are two main types of witnesses: lay witnesses and expert witnesses. Lay witnesses share their personal observations and experiences, while expert witnesses provide specialized knowledge based on their qualifications in a specific field.

Additionally, the term "witness" can refer to someone who observes the signing of important documents, such as contracts or wills, and confirms that the signing occurred in their presence.
